Doc: update v10 release notes through today.
Add item about number of times statement-level triggers will be fired. Rearrange the compatibility items into (what seems to me) a less random ordering.

Also, if there were statement-level triggers on a table affected by a

they could fire more than once per outer SQL statement. This is

<para>

The size of the compiled-in DH parameters has been increased from

|
1024 to 2048 bits, making DH key exchange more resistant to
|
||||||
|
brute-force attacks. However, some old SSL implementations, notably
|
||||||
|
some revisions of Java Runtime Environment version 6, will not accept
|
||||||
|
DH parameters longer than 1024 bits, and hence will not be able to
|
||||||
|
connect over SSL. If it's necessary to support such old clients, you
|
||||||
|
can use custom 1024-bit DH parameters instead of the compiled-in
|
||||||
|
defaults. See <xref linkend="guc-ssl-dh-params-file">.
